Contact and logic level input/switch driving output 1 input 1 output

Overview

^ Isolated safety barrier at operating side: PHC-11TF-14, switch input and output, single input and single output.

^ Safety barrier can convert the input quantity of contact switch and logic level in safety area into the driving quantity of intrinsically safe equipments, and output it to the field of dangerous area, so as to control solenoid valve, audible and visual alarm, etc.

^ The status indicator has red and yellow light colors, when alarm then the light is red, when it is with the output solenoid valve, then the light is yellow. This product needs an external 20~35VDC power supply

* bus terminal for power supply, please see the appendix for details.
